Tape that visually indicates a tear site of a section of tape from a longer length of tape and that visually distinguishes the tear site from the remainder of the length of tape, so that the end of the roll can be readily identified. The tear site becomes visible upon the reaction of a chromogenic material. The reaction of the chromogenic material is initiated by tearing of the tape, so that a visible mark or indicator results from tearing or cutting the tape.
